A man who took 17 hostages in a Sydney cafe was killed by security forces who stormed the building.
Two other people were killed and four were injured.
Australian police locked down the centre of the country's biggest city on Monday after an armed man walked into a busy downtown Sydney cafe, took hostages and forced them to display an Islamic flag, igniting fears of a jihadist attack.
Police said they knew of one armed assailant involved in the incident at the Lindt chocolate cafe in the heart of Sydney's financial district, but there could be more.
Police, including paramilitary officers, cordoned off several blocks around the cafe as negotiators tried to defuse one of the biggest security scares in Australia for decades. Snipers and a SWAT team took up positions around the cafe and police helicopters flew overhead.
